Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468042, here are decompositions:

  • 79 + 2147467963 = 2147468042
  • 229 + 2147467813 = 2147468042
  • 241 + 2147467801 = 2147468042
  • 283 + 2147467759 = 2147468042
  • 331 + 2147467711 = 2147468042
  • 373 + 2147467669 = 2147468042
  • 463 + 2147467579 = 2147468042
  • 571 + 2147467471 = 2147468042

Showing the first eight; more decompositions exist.
